	OFFSET	`1,5`
	EXAMPLE	`For n=1 and 2 the nearest prime neighbors are 2 and 2, with distances 1 and 0. Closest primes around 8! are 40289 and 40343 with 31 and 23 distances so a(8)=23`
	MAPLE	`with(numtheory): [seq(min(nextprime(i!)-i!, i!-prevprime(i!)), i=3..100)]; # a(1) and a(2) computed individually`
	CROSSREFS	`Essentially the same as A053714.` `Adjacent sequences: A056749 A056750 A056751 this_sequence A056753 A056754 A056755` `Sequence in context: A141597 A119727 A046739 this_sequence A053714 A033933 A108267`
	KEYWORD	`nonn`
